Once you reach the endgame, if you have a robot, spawn the robot during the fight, and there seems to be enough Rakk respawning to keep your robot alive indefinitely, giving you XP, and more money/loot. Here I've got 175 kills on the robot alone, as shown in the icon near the bottom, but it went to 400 by the time we were done checking out loot. :)http://cloud-2.steampowered.com/ugc/...CE5242009E465/
